USDA has reported that there were five states in 2011 that generated more than $5 billion in corn sales:
- Iowa -- $14.5 billion
- Illinois -- $12.3 billion
- Nebraska -- $9.4 billion
- Minnesota -- $7.0 billion
- Indiana -- $5.3 billion
These five states generated 63.4% of all corn sales in the U.S. for 2011. The states of Ohio, South Dakota and Wisconsin each generated between $3 and $4 billion of corn sales.
For soybeans, there was only one state over $5 billion and that was Iowa, at $5.5 billion, with Illinois at $4.95 billion. The top three corn states generated more in sales than all of the U.S. soybean production of $35.8 billion.
There were only four wheat states that generated more than $1 billion in sales:
- Kansas -- $2.0 billion
- North Dakota -- $1.7 billion
- Montana -- $1.3 billion
- Washington -- $1.1 billion
Iowa generated more in corn sales at $14.5 billion than the whole U.S. wheat crop of $14.4 billion.
We can see why corn is king in the U.S. based on these statistics.
